IEC 61000-4-2 standard for ESD performance.

APPLICATIONS

• Charging circuits.

GENERAL DESCRIPTION

The UBA2007 is an intelligent charge switch IC for pulse

mode charging applications. With its integrated low ohmic

power switch it is designed for charging of 1-cell Li-Ion or

3-cell NiMH batteries in either a pre-charge or fast charge

mode. The reverse mode of the UBA2007 allows the

supply of accessories connected to the charger pin.

Several integrated safety mechanisms such as current

limitation, overvoltage protection, thermal protection and

ESD guarantee fail-safe operation.
